clinical manifestation of premature ejaculation

Premature ejaculation is one of common clinical symptoms of sexual disturbance. It is difficult to define premature ejaculation exactly and different people have different perspectives. Masters and Johnson defines premature ejaculation is that female with sound sexual function can not be satisfied in 50% cases of normal sexual intercourses, because the male part fail to control sufficient time before ejaculation. Kaplan deems it is sound when 5 or more minutes can be maintained after penile insertion or both sides of couple are satisfied of their sexual intercourse without any effort to delay the ejaculation. It is also reported that the case that 75% male can maintain a duration of 2 to 6 minutes or less after penile insertion before ejaculation is sound. It is easy to diagnose the ejaculation which occurs before erect mentula insertion into vagina as premature ejaculation clinically. However, it is not so easy for deciding how long of the sexual intercourse duration for the one whose penis can insert vagina is sound. Generally , premature ejaculation refers that ejaculation occurs before erect penile insertion into vagina, merely at the moment of inserting or at the moment merely after insertion but before back and forth movement, and penis soon becomes weary and reaches refractory period. Duration of male intercourse from the beginning to the ejaculation depends on the age which the man is at, the man's constitution. The duration of the young is relatively long and gradually short after prime of one's life. It is also prolonged by the increasing sexual experience. There are various causes of premature ejaculation. However, ejaculation in following cases should not be diagnosed as premature ejaculation. In the evening of new wedding, husband and wife are excited for the first experience of sexual life, therefore ejaculation occurs at the touch moment of sexual organs or merely after penis insertion into vagina. Husband and wife meet again after a long separation, therefore they are comparatively sexually excited, and ejaculation occurs sooner. In the cases above, premature ejaculation will be improved with the together life of couple going, and does not need to be treated.
